HVA1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.1HG0080020 (HVA1) on barley chromosome 1H encodes a late embryogenesis abundant (LEA) protein, specifically LEA3, and is annotated with L-lactate dehydrogenase (cytochrome) activity. The gene is associated with protein stabilization, response to freezing, cold acclimation, stomatal closure, ABA signaling, seed germination, and embryogenesis. It localizes to the cytosol and nucleus. In barley, HVA1 has been linked to freezing tolerance, and broader associations include drought tolerance, salinity tolerance, heat tolerance, and responses to high and low temperature stress. The gene is also connected to relative chlorophyll content, flavonoid content, and chlorophyll content. Studies of related genes in other species link the LEA3 family to desiccation tolerance.
